I have always found preflop strategy interesting, but small habits can become costly over a large sample. Range construction, open sizes, blind defense and three-bet decisions may look fine individually while creating recurring problems. Because of that, I started exploring specialized preflop analysis instead of relying only on general charts. I came across https://baseanalise.com/ and found the idea of reviewing key moments from a player’s own database useful. Focusing on one stage of the game seemed like a practical way to strengthen the basics before moving to more complex postflop situations. I also noticed that analysis can be adapted to different formats, where ranges and decisions may vary. During my research, I encountered the phrase advanced poker training and realized that structured training and personal database analysis serve different purposes. Training can develop theoretical knowledge, while reviewing actual hands can reveal which habits are affecting EV. What I value most is receiving practical recommendations that can be applied during future sessions. For me, the logical approach is to identify the main preflop weaknesses, work on them consistently, and then review new data to see whether those tendencies have improved.
